Oprah Winfrey blames her recent 20 pound weight gain on a thyroid
condition.
The talk show queen, 53, has publicly battled with yo-yoing weight for
years.
In the October edition of U.S. magazine 'O', Winfrey reveals that a
thyroid problem caused her weight to soar and left her "sluggish,
exhausted and stressed".
She says, "First hyperthyroidism, which sped up my metabolism and
left me unable to sleep. (Most people lose weight. I didn't.) Then
hypothyroidism, which slowed down my metabolism and made me want to sleep
all the time. Most people gain weight. I did! Twenty pounds!"
